Abstract:
We present a novel method for monocular hand shape and pose estimation at
unprecedented runtime performance of 100fps and at state-of-the-art accuracy.
This is enabled by a new learning based architecture designed such that it can
make use of all the sources of available hand training data: image data with
either 2D or 3D annotations, as well as stand-alone 3D animations without
corresponding image data. It features a 3D hand joint detection module and an
inverse kinematics module which regresses not only 3D joint positions but also
maps them to joint rotations in a single feed-forward pass. This output makes
the method more directly usable for applications in computer vision and
graphics compared to only regressing 3D joint positions. We demonstrate that
our architectural design leads to a significant quantitative and qualitative
improvement over the state of the art on several challenging benchmarks. Our
model is publicly available for future research.
